COLLAPSIBLE METAL BOX.

Application filed July as,

To all whom it may concern:

' Be it known that I, RICHARD S. RnrNolms, citizen of the United States, residing at Louisville in the county of Jefferson and State of kentucky, have invented certain new and useful Improvements in Collapsible Metal Boxes; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others, skilled in the art to which it appertains to make and'use the same.

This invention relates to new and useful improvements in receptacles and particu- .larly to. a receptacle which is constructed in such a manner as to provide a practically airtight package when the same is arranged in its folded position.

Another object of the present invention is the provision of a folding package com prising an outer layer of foil cardboard blank adapted to be folded into a boxlike receptacle, the edges of the foil projecting beyond the ed es of the receptacle and adapted to be fold inwardl whereby the contents of the package will e securely wrapped. v v A further object of the present invention is the provision of a wrapper comprising a central core portion of fairly heavy paper and provided with an outside foil wrapper larger than the central core portion, whereby when the wrapper is folded around the goods into a box form, it will provide an air-tight closure by having the side POI? tions of the foil wrapper folded over the end of the box wrapper, andas this outside wrapper is of foil it will securely retain itself in position after being folded to provide for suitable closure for. the ends of the inside folded parts.

With the above and others objects in view, the invention consists in the novel features and oontruction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the clann and shown in the accompanying. drawings, in whichl I Figure 1 is a trating a receptacle constructed in accordance with my invention;

Fig. 2 is a perspective view illustrating the same in partially folded condition.

of the folding type and an inner as shown in Figure plan view of a blank, illus 1920. Serial No. 398,865.

Figure 3 is an end elevation showing how first a central wrapper portion which is formed of comparatively heav wrapping paper and creased to provide fi ve foldable sections. These foldable sections are generally indicated in the accompanying drawings y the numerals 1 and 2. Arranged upon one face of these foldable cardboard sections is a sheet of waxed paper, indicated by the numeral 3. As illustrated in the drawings, this sheet 3 extends at its longitudinal edges beyond the edgesof the foldable sheet and has one of its transverse edges extending beyond the end of the fold-able center sheet so that when to provide for the sealing of the package end portions thereof.

In order" to" provide a suitable outside wrapper for the packa e, I have attached to the Waxed sheet 3, a s eet of foil 4, which is adapted to enclose the entire receptacle when the same is in its folded position as shown in Figure 3. In securing the inside receptacle to the waxed sheet 3, the sections 2 are attached to the sheet 3 while the sections 1 and 1 at each end of the foldable center sheet are free from the waxed sheet so that when the device is folded the section can be readily attached or connected to the section 1 by retaining the receptacle in its folded position.

It will be noted that the section 1* is cut away in its end portions to provide the tabs 5 which are to be inserted within the slots 6 formed in the end ortion to thus retain the receptacle in its olded position. The sections 1 and l will have to be entirely as free from the waxed sheet 3 so that when the central foldable member is folded up 2, the tabs5 can be readily i serted through the slot 6 from the outside of the section 1 as clearly illustrated in Figure 2.

When it is desired to wra an article with this improved wrapper, t e article is placed on the first-of the number'2 sections, adjacent the section 1 and the remaining number '2 sections are folded over onto the article, while section 1 is folded inwardly toward the article and engaged by the section 1 to retain the wrapper in its folded position above the article. As one end of the outside wrapper projects beyond the end of the inside foldable wrapper, this projection will extend beyond the, meeting edges of the inside wrapper so as to entirely overlap the meeting edges of this inside wrapper and to provide a comparatively air-tight connection at this point. As the side portions of the sheets 3 and 4: project beyond the side portions of the inner foldable wrapper, these projected side portions will constitute the ends of the package when it is folded into the position illustrated in Figure 2. These extended end portions can is to be enclosed therein,

then be folded inwardly as illustrated in Bi ure 3 to provide a substantially airtig t end for the wrapped package. From this it will be apparent that the wrapper can be readily applied to the article which has been securely wrapped it will provide a substantially air-tight closureinview of the fact that the outside wrapper is made of tinfoil or similar material so that when the end portions are folded inwardly to the position illustrated in Figure 3 they will be 7 beyond the and after the same I retained in position by the weight of the foil. If desired, the end portions can be slightly indented to assure the PIOPQR sealin of the package.

hat I claim is:

A receptacle of the class described consisting of a wrapper portion formed of comparatively heavy wrapping paper and creased to provide a plurality of foldable sections adaptedtobe folded to form a substantially rectangular body, tabs formed on one end of said paper, said paper being provided withtab receiving slots at its opposite end, a sheet of waxed paper secured to one face of the wrapping paper and having its longitudinal edges extending beyond the edges of the wrapping paper and also having one of its transverse edges projecting end of the foldable wrap-pin paper, a sheet of foil secured to the waxe sheet and adapted to entirely cover the same and the longitudinal edges of said waxed and foil sheets'being adapted to be folded inwardly upon the ends of the body when the body is in a folded position ,to entirely close the endsthereof.

' In testimony whereof I afiix my signature.

RICHARD S. REYNOLDS.
